Creating a Taxonomy of Local Boards of Health Based on Local Health Departments' Perspectives.

OBJECTIVES: To develop a local board of health (LBoH) classification scheme and empirical definitions to provide a coherent framework for describing variation in the LBoHs. METHODS: This study is based on data from the 2015 Local Board of Health Survey, conducted among a nationally representative sample of local health department administrators, with 394 responses. The classification development consisted of the following steps: (1) theoretically guided initial domain development, (2) mapping of the survey variables to the proposed domains, (3) data reduction using principal component analysis and group consensus, and (4) scale development and testing for internal consistency. RESULTS: The final classification scheme included 60 items across 6 governance function domains and an additional domain-LBoH characteristics and strengths, such as meeting frequency, composition, and diversity of information sources. Application of this classification strongly supports the premise that LBoHs differ in their performance of governance functions and in other characteristics. CONCLUSIONS: The LBoH taxonomy provides an empirically tested standardized tool for classifying LBoHs from the viewpoint of local health department administrators. Future studies can use this taxonomy to better characterize the impact of LBoHs.

Recent advances in public health systems research in the United States.

Recognizing the public's health is the outcome of dynamic, adaptive, and complex systems of agencies; infrastructure, relationships, and interactions that dictate how to improve health outcomes; and reducing health risks in a population is based on systems thinking and evidence. New methods such as network analysis and public health practice-based research networks demonstrate the potential for new insight to our understanding of how systems and infrastructure influence population health. We examine advances in public health systems research since 1988 and discuss the relevance of this type of research to public health practice. We assess the current infrastructure for conducting public health systems research, suggest how the research infrastructure can be improved, and conclude with a discussion of how health reform in the United States will require research focused on understanding the adaptive complexity inherent in public health and health care systems and strengthening the systems research infrastructure.

Secondary analysis of a marketing research database reveals patterns in dairy product purchases over time.

OBJECTIVE: Development of a method using marketing research data to assess food purchase behavior and consequent nutrient availability for purposes of nutrition surveillance, evaluation of intervention effects, and epidemiologic studies of diet-health relationships. DESIGN: Data collected on household food purchases accrued over a 13-week period were selected by using Universal Product Code numbers and household characteristics from a marketing research database. Universal Product Code numbers for 39,408 dairy product purchases were linked to a standard reference for food composition to estimate the nutrient content of foods purchased over time. SUBJECTS/SETTING: Two thousand one hundred sixty-one households located in Victoria, Texas, and surrounding communities who were active members of a frequent shopper program. ANALYSES: Demographic characteristics of sample households and the nutrient content of their dairy product purchases were analyzed using frequency distribution, cross tabulation, analysis of variance, and t test procedures. RESULTS: A method for using marketing research data was successfully used to estimate household purchases of specific foods and their nutrient content from a marketing database containing hundreds of thousands of records. Distribution of dairy product purchases and their concomitant nutrients between Hispanic and non-Hispanic households were significant (P<.01, P<.001, respectively) and sustained over time. APPLICATION/CONCLUSIONS: Purchase records from large, nationally representative panels of shoppers, such as those maintained by major market research companies, might be used to accomplish detailed longitudinal epidemiologic studies or surveillance of national food- and nutrient-purchasing patterns within and between countries and segments of their respective populations.
